Although several methods have been proposed for improving those characteristics, they have never been put into practice. We have focused on the transfer function of the catheter manometer, and made a pilot system, using the natural observation method. This method has been suggested as a means of studying the structure of the instantaneous waveform. In this manner, we were able to increase the bandwidth in the frequency domain and reduce the ringing in the time domain. Correction was performed automatically, using a step wave. Reproduction bf the waveform with a flushing device, was a task of equal simplicity, that allowed us to estimate the system parameters so that the response waveform became step-like. In the experiment, our system provided distortion-free left-ventricular pressure waveform measurements and exact evaluation of the cardiac pumping system. The values obtained came much closer to the original figures arrived at by the catheter-tip manometer system.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/trans_online/","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright@1992 IEICE"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826272","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168532","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hori, Jun-ichi"}],"nameIdentifiers":[{"nameIdentifier":"6379","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saitoh, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"6380","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kiryu, Tohru"}],"nameIdentifiers":[{"nameIdentifier":"6381","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iijima, Taizo"}],"nameIdentifiers":[{"nameIdentifier":"6382","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"E75-D_6_909-915.pdf","filesize":[{"value":"603.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"E75-D_6_909-915.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1956/files/E75-D_6_909-915.pdf"},"version_id":"b6f28efa-f3f4-4e6f-a3fd-ee0511ba6c3a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"automatic correction","subitem_subject_scheme":"Other"},{"subitem_subject":"natural observation method","subitem_subject_scheme":"Other"},{"subitem_subject":"catheter manometer system","subitem_subject_scheme":"Other"},{"subitem_subject":"left-ventricular pressure waveform","subitem_subject_scheme":"Other"},{"subitem_subject":"lushing device","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Automatic Correction of Left-Ventricular Pressure Waveform Using the Natural Observation Method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Automatic Correction of Left-Ventricular Pressure Waveform Using the Natural Observation Method"},{"subitem_title":"Automatic Correction of Left-Ventricular Pressure Waveform Using the Natural Observation Method","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-31"},"publish_date":"2012-10-31","publish_status":"0","recid":"1956","relation_version_is_last":true,"title":["Automatic Correction of Left-Ventricular Pressure Waveform Using the Natural Observation Method"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:48.369812+00:00"}
